theres a garage not too far, infact theres at least 3 i know *used* to give em out willy nilly, ones shut down due to this, apparently got caught testing the light height with a broomstick and black ink lines also not bothering to check the cars underneath.

One of the others, the fella died and so did the MOT certs. (£10 each at the time, back in the late 80's)
The other went cosher and do the full MOT now a days as he does infact earn good money from the customers, who infact trust him
